Sensor Verdict: The LCM system generated a RED (Brake) circuit alert on trailer GV2202496. Based on the available evidence, the sensor result is classified as Inconclusive with low confidence (35%). The technician was unable to determine the root cause of the RED circuit alert ('CAUSE TBD'), and no brake circuit defect was confirmed or ruled out using the required PCT TechAssist verification process. The alert may reflect a real fault, a transient condition, or a device configuration issue, but the investigation was insufficient to resolve this question.

Photo Evidence: Seven photos were submitted with this work order, but none of them meet the procedural requirements for LCM troubleshooting documentation. Photos 1 and 6 show the exterior of the trailer with the Xirgo XT4964 mounting bracket open and the device absent or removed — these appear to be 'before' installation shots. Photos 2 and 7 show the Xirgo XT4964 device label (Serial #: 252227827, IMEI: 863554071377982) up close. Photos 3 and 4 show the Xirgo unit mounted in its bracket on the trailer wall, with Photo 4 notably showing two green LEDs illuminated on the device, suggesting it is powered and operational. Photo 5 shows the interior of a wiring junction box with a dense, disorganized bundle of multi-colored wires — this could serve as a partial nosebox photo, but it is not clearly identified as such and does not show the LCM insert or nosebox connectors in a diagnostic context. Critically, there are no photos of any trailer lights illuminated, no TechAssist app screenshot showing circuit verification, and no clear evidence of brake circuit inspection. The photos collectively document device installation/re-activation but not a lighting circuit inspection.
